' QAN-FILLINGMACHINE.

Specification of Letters Patent.

Application filed J'nly17, 1911. Serial No. 639,072.

To all whom it mciy concern.

Be it known that I, EDWARD B. GAGE, citizen of the United States, residing at Kahoka, in the county of Clark and State of Missouri, have invented'certain new and useful Improvements in Can-Filling Machines, of which the following is a specification. a

The present invention relates to certain new and useful improvements in'machines of that general type which are employed for filling cans or other receptacles with some liquid material such as milk, the primary object of the invention being the provision of a can filling machine which embodies novel features of construction whereby a large number of cans or the like may be accurately filled in a comparatively short period of time and with a small amount of labor.

A further object of the invention is the provision of a can filling machine which is comparatively simple and inexpensive in its construction, which can be easily cleaned and maintained in a sanitary condition, and which will operate in a quick and effective manner to accomplish the desired result.

With these and other objects in view, the invent-ion consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claims.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a top plan view of a'can filling machine constructed in accordance with the invention, portions being broken away. Fig. 2 is a side elevation thereof, portions being broken away and shown in section. Fig. 3 is an end view of the machine, portions being broken away and shown in section, and Fig. 4: is an enlarged sectional view through one end of the tank.

Corresponding and like parts are referred to in the following description and indicated.

' in all the views of the drawings by the same reference characters.

Specifically describing the present invention, the numeral 1 designates the support ing frame, which may be of any suitable construction, and upon which the tank-2 15 mounted. A supply pipe 3 extends downwardly into the tank at one end thereof and terminates ata pointtoward the bottom of the tank, the said pipe serving to lead the milk or other liquid into the tank, and

.the flow of milk or liquid through the pipe being controlled by a valve 4. A drain pipe 5 is also shown as leading from the bottom of the tank, the said drain ipe being provided with a valve 6 which is closed during the operation of, the machine.

A series of measuring cups 7 project upwardly from the bottom of the tank and terminate at a point below the top of the tank, preferably about midway between the top and bottom thereof. These measuring cups are shown as being substantially cylindrical in shape, and are of such a size as to contain the exact amount of milk or other liquid which it may be desired to run into each of the cans being filled. A discharge opening 8 is provided in the tank bottom for each of the cups 7, the said discharge opening being normally closed by a vertically movable valve rod 9. The upper end ofthe discharge opening 8 is flared at S so as to bring theend of the valve rod into the opening when the said valve rod is lowered into a closed position, while a groove 10 on the lower side of the tank bottom surrounds each of the openings 8 so as to provide the equivalent of a short spout and cause the liquid to emerge through the discharge opening in a well defined stream and prevent the liquid crawling along the plate and dropping off at wrong places.

Each of the valve rods 9 is provided with a weight 11 which normally tends to move the same downwardly into a closed position and which by being adjustable up and down on the valve rod and held in the required position by a set screw makes a displacement which will control the exact amount of liquid in each cup, while the upper end of each of the valve rods is engaged by a frame 12, the said frame being formed with arms 12 which extend over the sides of the tank 2 and rest upon the same when the frame is lowered so as to bring the valve rods into a closed position. A displacement Patented Sept. 1'7, 1912.

as to permit th'e milk within;the measuring Inen't member 13 is again lowered within the 1 task so, as to. permitj theframe 12 and valve s 9 to drop'in'to closed position. I A con- Ztinued downward movement of the displacement member serves to again fillthe 1118218 cups '7, and thisnperatioiimay vbe'c o-ncups 7 to flow through the discharge; openmgs 8 intothe respective cans 14- arranged 'u'nder'the openings, the capacity of the said i measuring cups correspondingwith thesize ofthe cans" After the contents of the Imeasurmg. cups have been drained, the displacetinned indefinitely, Projecting upwardly from each end of the vje'cting om a shaft 19 journaled upon one 3 side of the. supporting frameil' the' said rock shaft being providedwith an operating displacement member 13 is an arm15, the

upperendsof the said arms being connected ,tovertically disposed plun'gers l'6 which' are slidably mounted upon, the supporting 1 frame and. extend downwardly below the tank, Each of these plungers 16 is connected'b a'link' 17 to a crank arm 18 prohandle 20. A third crank arm 21 also pro-- jects" from the rock shaft 19 and is engaged the dis lacement float 13 in an elevated position.

' as has been previously describeda .T-he cans '14,.or other receptacles 'to be filled are arranged'upon a tray 23 or other 'carrying'device or holding device whichis adapted to be slid into and outof operative upon the main frame} forengaging the cans 14 when\they are properly disposed under the discharge openin'gsQB. This positioning rail may extend around three 'sldes' of the v group oficans'upon' the. tray. 'After the cans have'been filled, the tray 23 may be withdrawn and; another trayjfilled with empty cans slid into position, and the appa- 'ratus will admit of the'cans being accurately having a discharge opening in the bottom I filled as quickly as they can be placed'in and out of position.

Having thus described the invention, what I claim as new and desire to secure by Let-j ters Patent, .is:

'1. A can fillingmachme including a-tank and means for raising and lowering the displacement member, the saiddisplacement member upon its, upward movement. engaging thebefore mentioned frame which'is arranged'in the path thereof so as to elevate the Valve rod and permit the liquid within the measuring cup to be discharged through the before mentioned discharge opening.

2. A can filling machine including a tank having a discharge opening in the bottom thereof, a measuring cup projecting up-z wardly from the bottom of the, tank and surrounding the discharge opening, a valve.

rodlprojectmg upwardly through the .meas-,-.-

uring cup and controlling the discharge opening, a frame connected to the valve rod and normally restin loosely upon the top of the tank when the valve rod is in a closed position, a displacing weight adjustably mounted upon the valve rod so as to ,hold the valve rod normally in a lowered and closed position, said displacing weight forming a means for regulating the exa'ct amount of liquid in'the cup, a vertically movable displacement member mounted within the t nk and serving when lowered to cause the liquid withinthe .tank to overflow into the measuring cup,and means 'for raising and lowering the displacement member, the said displacement member upon its upward --movement engaging the before mentioned frame which is arranged in the paththereof so as to lift the valve rod and permit the liquid'within the measuring cup to be discharged through the discharge opening 3. .A can filling machine including a tank having a discharge opening in the bottom thereof, a'measuring. cup surrounding the discharge opening and projecting upwardly from the tankbottom, a valve rod controlling the discharge opening and projecting upwardly throu h the measuring cup, a
